Two-dimensional layered nanomaterials, such as graphene and metal sulfides/ Selenides like Tungsten disulphide (WS2), Molybdenum disulphide (MoS2) and Niobium diselenide (NbSe2) etc. are evaluated and compared based on their standalone ability to work as an effective Electromagnetic Interference Shielding Material in a polymer matrix. Liquid exfoliation technique is selected for preparation of these 2D Nanosheets. Characterization of 2D materials was performed by Raman, AFM and UV VIS techniques. The 2D Nanosheets were then evaluated based on their performance as effective shielding material. The assessment of their EMI shielding properties and conductivity was determined along with the effect these 2D materials add to the polymers shielding capabilities and mechanical strength along with dielectric properties was evaluated to determine the best possible filler material.
